  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg - splitting, overlaying and selecting frame range in multiple input/outputs with complex video filter producing empty output

    11 octobre 2017, par Josep Carner

    I am trying to use ffmpeg to apply multiple filters -single input, multiple outputs-. In concrete, I am splitting the output in two, then applying an overlaying patch to one of those streams, split again and select a time range. The command I am using is :

       ffmpeg \
    
    -i ./dataset_test/videos/jz_10_huron_barstow.mkv \
    
    -an \
    
    -sn \
    
    -loglevel error \
    
    -filter_complex \
    
        "[0:v]split=2[L_in][F_in];
    
         [L_in]
    
            crop=226:307:21:74,scale=200x200,setdar=200:200,split=2\
    
         [L_in_0][L_in_1];\
    
         color=#808080:226x307,setpts=PTS-STARTPTS[L_PATCH];\
    
         [F_in][L_PATCH]
    
            overlay=21:74:shortest=1,scale=200x200,setdar=200:200,split=2\
    
         [F_in_0][F_in_1];\
    
         [F_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_0];\
    
         [F_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_1];\
    
         [L_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_0];\
    
         [L_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_1]\
    
         "\
    
    -map [F_0] -an -sn ./out/jz_10_huron_barstow/F/0_F.mp4\
    
    -map [F_1] -an -sn ./out/jz_10_huron_barstow/F/1_F.mp4\
    
    -map [L_0] -an -sn ./out/jz_10_huron_barstow/L/0_L.mp4\
    
    -map [L_1] -an -sn ./out/jz_10_huron_barstow/L/1_L.mp4\

    For some reason, 0_F.mp4 is empty and 1_F.mp4 is cropped. My intuition is that it has something to do with applying splitting + overlaying + selecting. I think at some point some filter before select is changing the PTS of the frames in some way select is not properly discarding them, but I honestly don’t know how to solve it. Some insights :

    1. L_0 and L_1 are fine (no overlay is used in those two)

    2. If I suppress L outputs everything works fine (no "split" is needed at the beginning)

    Could someone provide some light ? I don’t really know what else to try.
    The logs with loglevel 40 are (some repeated lines ommited) :

  • ffmpeg generating out of sync audio/video file

    2 mars 2013, par marcelorocks

    I am trying to convert a flv video to mp4 using a264, but the result video has a out of sync audio/video. Audio seems ok but video seems slow and therefore out of sync. I am a newbie on video conversion so any help is appreciated.

    Here is the command I am running :

    /opt/local/bin/ffmpeg -i complaint.flv -f mp4 -vcodec libx264 -acodec aac -copyts -strict experimental -fpre /opt/local/share/ffmpeg/libx264-lossless_slow.ffpreset -ab 44k -threads 0 -crf 23 complaint.mp4

    And the printout :

    Desktop  /opt/local/bin/ffmpeg -i complaint.flv -f mp4 -vcodec libx264 -acodec aac -copyts -strict experimental -fpre /opt/local/share/ffmpeg/libx264-lossless_slow.ffpreset -ab 44k -threads 0 -crf 23 complaint.mp4

  • FFmpeg produces empty file sometimes

    30 avril 2024, par Matan Malka

    I am currently using ffmpeg and attempting to convert multiple PNG files to MP4 video.

    


    My command is :

    


    ffmpeg -y -r 10 -i "videos-reporter/MC4xMzg3NDI1MTY2Mjg1MTk=/b8a7ee17d8ecfd199edbc5edc9691698/screenshots/%04d.png" -vcodec libx264 -pix_fmt yuv420p -vf "scale=1200:trunc(ow/a/2)*2","setpts=3.0*PTS" "videos-reporter/MC4xMzg3NDI1MTY2Mjg1MTk=/b8a7ee17d8ecfd199edbc5edc9691698/video.mp4"


    


    Sometimes, I'm unsure when the ffmpeg creates a 1kb empty video file that cannot be played.
